Ok so I am putting my motor together with stud mount rockers do you have set the preload on stud mounted rockers by following the firing oreder or can you just go through and set them?

If you can rotate the engine easily, just go down each bank.
You only have to ensure you're on the base circle of the lobe.

As 347 said, the main thing is the lifter of the valve to be adjusted must be on the base circle of the cam.

It's easiest just to follow the firing order, as the lifters will be on the cam base circle in that sequence.

You must have the lifters on the base circle, ie, valve fully closed to adjust them.

Two ways:

a-rotate the engine and set them in order of the firing order, one cylinder at a time.

b-You can index the motor to three positions and it will get all 8 cyls on the base circle. The positions are in most books on sbfs.

I prefer just going through the firing order one at a time, as its easier not to miss anything.

I went through and set one bank and then the other bank making sure that I was on the base circle and allowing each lifter to bleed down first but I did not set them in the actual firing order is this an ok way to do that?

If each valve was on the base circle during adjustment, yes, it's okay. Using the firing order is just a more "fool proof" way. Less likely to miss a cylinder.
